In order to have a TV efficient Lizardmen team you have to skill up your Sauri, and just 1-2 Skinks as ball carrier/one turner, the rest of the Skinks is disposable fodder (thus they must be cheap).

Bull. You need 'em all skilled, so if one drops, another can pick up the slack. They're still disposable fodder, but keep 'em running as long as you can.

If they are special (they have either +1 MA, +1 AG, or they have rolled a double) yes you keep them, if they didn't roll +1 MA, +1 AG or a double at their 2nd skill fire them and trim your TV. This way you roll more times, you have less TV bloat and you have more chances of rolling a good skill, moreover, if they become too expensive they are not disposable anymore (100 TV on a fragile Stunty player? No thanks). Yes, you can protect a couple of good Skinks (namely the ball carrier and/or the one turner), but protecting all Skinks is hard.
A two skills Skink requires 16 SPPs. With 32 SPPs (16 SPPs each Skink) you have 4 skill rolls (2 per each Skink), while if you stack the same amount (32 SPPs) on a single, not special Skink you have just 3 rolls and less chances of rolling something good.

Makes sense, but I have a hard job firing them because they look so cute.

Yet another reason why you should NEVER give your Skinks cute-sounding names. Nobody ever shed a tear because "Skink C" suffered a broken collarbone or "Skink F" went three levels without a remarkable skill-up.

I wish we could rename zombies, I like keeping to my theme of "Fallen Hero #7847827574875385678934573485389475398" but I've gotten two to my ranks from other teams. I -really- wish there were zombified figures for other races...

Generally speaking I like to let players that have been stalwart performs die in the line of duty. I've had a 1 str skink that knocked around for quite awhile. He didn't even die. He was made of stern stuff. In the end I got rid of him to get under a tv cap and there just wasn't any other option. He was my top scorer for quite some time and had +mv, catch, and sidestep.

I've mentioned this in another thread, and really, it's probably all the same people reading it so this may be unnecessary, but whatever - I had my best Norse lineman fouler take a -str injury (he was DP and Sneaky git as far as skills at the time) and I decided i'd keep him since he left the pitch on a caught foul more often than not, and thus the -str wasn't the end of his "normal" use. Well he rolled a +AG on his next level, so now in addition to fouling, he can be an emergency ball hander or just use that extra AG to dodge into the backfield and stomp on some dude that was normally out of reach. In LEAGUE play I don't mind carrying some dead weight, because inducements very very rarely work out to equal the amount of TV they are replacing, to much fail involved with them.
